python3 中的Json序列化、反序列化 和 字符编码的问题解决

python3在通过Json往文件里写内容时中文字符被转成unicode编码

import json

class file_open(object):

    f = open('chooes_course.txt', 'r+', encoding='utf-8')

    def write_f(self,info):
        self.info = info
        file_open.f.write(json.dumps(self.info))

    def read_f(self):
        print(file_open.f.read())

    def __del__(self):
        file_open.f.flush()
        file_open.f.close()


members = {'张三': ['zs123', '56.8'], 'lisi': ['ls123', '47.2'], 'mologa': ['mologa123', '100']}
f1= file_open()
f1.write_f(members)

　打开choose_course.txt显示

{"\u5f20\u4e09": ["zs123", "56.8"], "lisi": ["ls123", "47.2"], "mologa": ["mologa123", "100"]}

　*如上 '张三' ==> '\u5f20\u4e09'

解决办法：

　　在dumps中加入参数 ensure_ascii=False

    def write_f(self,info):
        self.info = info
        file_open.f.write(json.dumps(self.info,ensure_ascii=False))

　　即可解决

{"lisi": ["ls123", "47.2"], "张三": ["zs123", "56.8"], "mologa": ["mologa123", "100"]}100"]}
